Robotic Discrete Network Assembly

This thesis criticizes current manufacturing processes heavily depending on complex temporary formwork and scaffolding, proposing an integration method of scaffolding as an actuated permanent equal member of the building structure.

Rethinking Scaffolding. Recent rapid development of computer-aided design (CAD) tools and computers give designers and architects possibilities to design and simulate complex geometries and building structures. Constructing this shapes require increasing complex formwork and scaffolding, temporary structures to support and hold building elements in place, removed and most likely wasted after building completion.

Lightweight Structure. A revisited building sequence also influences and initiates space to rethink the building structure itself. Lightweight structures are of interest for ages. From Antoni Gaudí’s Sagrada Familia, and his hanging chain models to Frei Otto’s tensile tent structures emphasizing smallest amounts of material used while maintaining performative properties.

Geometric Importance. Current development in digital fabrication methods and growing accessibility by all professions open up new opportunities for architecture in the 21st century. Rapid digital simulation helps us to calculate physical phenomena and predict possible outcome more precise and faster than ever. Advanced geometric thinking becomes increasingly valuable, especially for economic reasons. Through tools, in the genre of computer-aided manufacturing (CAM) the gap between advanced geometry in the digital and fabrication in the real world becomes smaller. The approach to be presented suggests a topology optimisation process with the objective of material reduction. A compression tension algorithm defines the positioning of segmented members of an integrated spatial network, actuated by a membrane wrapping strategy, replacing conventional formwork and scaffolding, as part of the lightweight building structure.
